Impact
The Shield module enables you to protect a site behind an HTTP basic authentication prompt, so that an unfinished or non-public site cannot be viewed, crawled or indexed by anonymous visitors.
Source excerpt · OSVThis vulnerability is mitigated by the fact that the configured Shield credentials must be guessable — a long, randomly generated password is not practically brute forceable — and by the fact that Shield is intended as a supplementary barrier in front of a site rather than the site's user access control systems.

Original source description
The Shield module enables you to protect a site behind an HTTP basic authentication prompt, so that an unfinished or non-public site cannot be viewed, crawled or indexed by anonymous visitors.
The module doesn't sufficiently limit the number of authentication attempts it will evaluate under the scenario where an anonymous visitor repeatedly submits basic authentication credentials.
This vulnerability is mitigated by the fact that the configured Shield credentials must be guessable — a long, randomly generated password is not practically brute forceable — and by the fact that Shield is intended as a supplementary barrier in front of a site rather than the site's user access control systems.
